Programming Notes<br />
SCAL: Programming method introducing InP1 and InP2 values by keyboard.<br />
tEAC: *Programming method where instrument learns actual values of InP1 and Inp2.<br />
Use Calibrator to set low value (Min. 4 mA.) at INP1 and high value (Max 20 mA.) at INP2<br />
InP1: InP2 : Input signal values corresponding to desired display dSP1 and dSP2 .<br />
dSP1: Display value corresponding to InP1.<br />
dSP2: Display value corresponding to InP2.<br />
LC 0: Programming unlocked.<br />
LC 1: Programming totally locked. (Show all parameters like dAtA) .<br />
Err: Error on programmed parameter.<br />
Stor: Stores the whole configuration parameters.<br />
ENTER: Enter programming mode and accepts data<br />
SHIFT: In programming mode selects mode or moves decimal point<br />
UP: In programming mode increases the value of the decimal point<br />
